Power Circuit Inspection

  1. Check voltage of power circuit
    1. Key "OFF".
    2. Disconnect FTPS connector.
    3. Key "ON".
    4. Measure the voltage between terminal 1 of FTPS harness connector and chassis ground.

      Specification: Approx. 5V

    5. Is the measured voltage within specification?

      YES 

      NO 

      • Go to step  2.
  2. Check Open or Short in power circuit inspection
    1. Key "OFF".
    2. Disconnect FTPS harness connector and ECM/PCM harness connector.
    3. Measure the resistance between terminal 1 of FTPS harness connector and terminal 3/C01-2 of ECM/PCM harness connector. (A/T)

      Measure the resistance between terminal 1 of FTPS harness connector and terminal 50/C01 of ECM/PCM harness connector. (M/T)

      Specification: Approx. 1Ω
